#4133005 WIP : Not Outrun

Posted by Stephen on Sat Oct 13, 2018 7:41 PM

This is crazy good work!




#4132910 Hard Driviní on the 8 Bits?

Posted by Stephen on Sat Oct 13, 2018 5:06 PM

Here we go.  Much better.  80,629,734 evaluations, normal distance 0.38.  Included are Rasta Final screenshot, Altirra screenshot, and XEX for real machine.  Enjoy, and thanks for the suggestion.

#4132881 1050 ROMs

Posted by Stephen on Sat Oct 13, 2018 4:14 PM

 

 

I'm not sure this is nugget of information that is lost, just something I overlooked, perhaps, when reading about ADC. Most online references, only make mention of the carry bit being set, not that it was used in the actual computation.  

 

Direct from the MCS6500 MOS programming manual:

 

"This instruction adds the value of memory and carry from the previous operation [emphasis mine] to the value of the accumulator and stores that result in the accumulator. 

The symbolic representation for this instruction is: A + M + C -> A"

 

All I can say is that its really good to have copies of these very old books.

Odd that many books wouldn't mention it.  Most that I read clearly stated that before using the add instruction, you have to clear the carry, and before subtract you have to set it for accurate results.

 

Cool that it was figured out though.  That's why I love these forums, there's a wealth of information and also, many people willing to share that information.  Let's keep those 6502s humming :)

Yes, but you run the chance of banding.  I think a good pixel artist would be better off using G2F (Graph-2-Font) for this.

 

Just because, here's a WIP.  Won't take long to finish this one out.  I still say G2F is the way to go for this, if nothing more, than for the smaller size file we'll get.

Damn.  Wouldn't you know it.  Got busy on other stuff, let this run to 1.4 Billion iterations.  It got down to a normal of 0.2, so this "can" be a perfect conversion.  I let it run too long, so there is a single bad line in it.  Also, forgot to center the image, so I will be restarting it.  Restarting now.  Here's screenshots of Rasta and Altirra.  Notice, the bad yellow line is NOT in the Rasta middle window :(

I'm pretty sure the title screen can be achieved by using Rasta Converter, right?

Yes, but you run the chance of banding.  I think a good pixel artist would be better off using G2F (Graph-2-Font) for this.

#4132660 Moon Patrol hack !

Posted by Stephen on Sat Oct 13, 2018 10:11 AM

Well, Rasta crashed last night for some reason, but it still managed to get a good conversion done before.  Altirra screenshot below.

#4132353 Atari 130XE not seeing 1050 when set to drive D2:

Posted by Stephen on Fri Oct 12, 2018 8:22 PM

I'd be interested in those, want to shoot me some atr's? I know some limit how many open at once but almost every thing I have does 1-4 minimum...

Stock Atari DOS 2.5 only does 1-2.




#4132335 Moon Patrol hack !

Posted by Stephen on Fri Oct 12, 2018 7:29 PM

This is a job for Rasta Converter! However, I can't find the exe...

Could be good with some pre-processing done to the initial image.

 

EDIT - OK, you made me do it.  Edits made, image processing.  Probably won't post anything until the morning.

#4132209 New version of ATARI 8 bit emulator released!

Posted by Stephen on Fri Oct 12, 2018 3:44 PM

 

It'd be more excusable it Xformer didn't have literally decades of poor emulation and broken promises behind it, the worst being for the customers who paid for it...

This must be the reason for the difference in styles (posting styles, i.e., perceived attitudes, etc.)  Been around a long time, but was never a paying customer of Xformer, so missed all the drama from back then.

 



#4131082 New version of ATARI 8 bit emulator released!

Posted by Stephen on Wed Oct 10, 2018 7:26 PM

Damn!  Way to blast back onto the scene!  PcXFormer is what re-kindled my Atari hobby just a few short years after my 1050 drive died.




#4130986 Size of the Atari 8-bit Community

Posted by Stephen on Wed Oct 10, 2018 5:02 PM

One of the "millions" here.  I love all my new upgrades, but I also have an unmodified 16kB 400 with membrane keyboard.  I was lucky - had my 1st machine since 82, and expanded my collection in the mid 90s when this "crap" was being thrown away.  No need to worry about stock or modified when you have over a dozen machines to choose from :)




#4130349 Jaguar Custom Game Hard Cases

Posted by Stephen on Tue Oct 9, 2018 5:39 PM

I need a higher res TI Dizzy CD cover! The only one I found was pretty pixilated! I am also looking for one for "CONCEPT" and "U-Fly" and the updated "Full Circle Rocketeer"

I could use a higher rez scan of that "lusty blonde wench" for research purposes of medi-evil times :).




#4128676 My Latest Tale Of Woe...

Posted by Stephen on Sat Oct 6, 2018 9:05 PM

Sorry for the mess - I would have been beyond pissed.  I'm getting better at not punching walls (or filing cabinets) as I get older.  Getting worse at cursing.




#4128469 Upcoming Jaguar SD Cartridge

Posted by Stephen on Sat Oct 6, 2018 11:55 AM

I just hope CD emulation works enough to drive the VLM :)  It was the only reason I bought the Jag CD in the 1st place.




#4128366 SRAM-Charger for Indus-GT - interest poll

Posted by Stephen on Sat Oct 6, 2018 9:11 AM

 

See my post a few minutes ago at page 5. I would prefer not to use SDX, I´m not sure if that works... untested by me.

SDX works perfectly fine, though I would highly recommend using trub terminal under SDX.
